Abstract:
Mangrove forests are the most important ecosystems on Pohnpei Island, Federated States of Micronesia, as the island communities of the central Pacific rely on the forests for many essential services including protection from sea-level rise that is occurring at a greater pace than the global average. As part of a multi-component assessment to evaluate vulnerabilities of mangrove forests on Pohnpei, mangrove forests were mapped at two points in time: 1983 and 2018. In 2018, the island had 6,426 ha of mangrove forest. Change analysis indicated a slight (0.76%) increase of mangrove area between 1983 and 2018, contrasting with global mangrove area declines. Forest structure and aboveground carbon (AGC) stocks were inventoried using a systematic sampling of field survey plots and extrapolated to the island using k-nearest neighbor and random forest species models. A gridded or wall to wall approach is suggested when possible for defining carbon stocks of a large area due to high variability seen in our data. The k-nearest neighbor model performed better than random forest models to map species dominance in these forests. Mean AGC was 167 ± 11 MgC ha-1, which is greater than the global average of mangroves (115 ± 7 MgC ha-1) but within their global range (37–255 MgC ha-1) Kauffman et al. (2020). In 2018, Pohnpei mangroves contained over 1.07 million MgC in AGC pools. By assigning the mean AGC stock per species per area to the map, carbon stock distributions were visualized spatially, allowing future conservation efforts to be directed to carbon dense stands.

Abstract:
The lithospheric mantle is of paramount importance in controlling the chemical composition of ocean island basalts (OIBs), influencing partial melting and magma evolution processes. To improve the understanding of these processes, the pressure–temperature conditions of mantle melting were investigated, and liquid lines of descent were modelled for OIBs on Pohnpei Island. The studied basaltic samples are alkalic, and can be classified as SiO2-undersaturated or SiO2-saturated series rocks, with the former having higher TiO2 and FeOT contents but with no distinct trace-element composition, suggesting melting of a compositionally homogenous mantle source at varying depths. Both series underwent sequential crystallization of olivine, clinopyroxene, Fe–Ti oxides, and minor plagioclase and alkali feldspar. Early magnetite crystallization resulted from initially high FeOT contents and oxygen fugacity, and late feldspar crystallization was due to initially low Al2O3 contents and alkali enrichment of the evolved magma. The Pohnpei lavas formed at estimated mantle-melting temperatures of 1486–1626 °C (average 1557 ± 43 °C, 1σ), and pressures of 2.9–5.1 GPa (average 3.8 ± 0.7 GPa), with the SiO2-undersaturated series forming at higher melting temperatures and pressures. Trace-element compositions further suggest that garnet rather than spinel was a residual phase in the mantle source during the melting process. Compared with the Hawaiian and Louisville seamount chains, Pohnpei Island underwent much lower degrees of mantle melting at greater depth, possibly due to a thicker lithosphere.

Abstract:
Microorganisms are central to the functioning of coral reef ecosystems, but their dynamics are unstudied on most reefs. We examined the microbial ecology of shallow reefs within the Federated States of Micronesia. We surveyed 20 reefs surrounding 7 islands and atolls (Yap, Woleai, Olimarao, Kosrae, Kapingamarangi, Nukuoro, and Pohnpei), spanning 875053 km2. On the reefs, we found consistently higher coral coverage (mean ± SD = 36.9 ± 22.2%; max 77%) compared to macroalgae coverage (15.2 ± 15.5%; max 58%), and low abundances of fish. Reef waters had low inorganic nutrient concentrations and were dominated by Synechococcus, Prochlorococcus, and SAR11 bacteria. The richness of bacterial and archaeal communities was significantly related to interactions between island/atoll and depth. High coral coverage on reefs was linked to higher relative abundances of Flavobacteriaceae, Leisingera, Owenweeksia, Vibrio, and the OM27 clade, as well as other heterotrophic bacterial groups, consistent with communities residing in waters near corals and within coral mucus. Microbial community structure at reef depth was significantly correlated with geographic distance, suggesting that island biogeography influences reef microbial communities. Reefs at Kosrae Island, which hosted the highest coral abundance and diversity, were unique compared to other locations; seawater from Kosrae reefs had the lowest organic carbon (59.8-67.9 µM), highest organic nitrogen (4.5-5.3 µM), and harbored consistent microbial communities (>85% similar), which were dominated by heterotrophic cells. This study suggests that the reef-water microbial ecology on Micronesian reefs is influenced by the density and diversity of corals as well as other biogeographical features.

Abstract:
Mesophotic coral ecosystems (MCEs) continue to be understudied, especially in island locations spread across the Indo-Pacific Ocean. Pohnpei is the largest island in the Federated States of Micronesia, with a well-developed barrier reef, and steep slopes that descend to more than 1,000 m. Here we conducted visual surveys along a depth gradient of 0 to 60 m in addition to video surveys that extend to 130 m, with 72 belt transects and 12 roving surveys using closed-circuit rebreathers, to test for changes in reef fish composition from shallow to mesophotic depths. We observed 304 fish species across 47 families with the majority confined to shallow habitat. Taxonomic and trophic positions at 30 m showed similar compositions when compared against all other depths. However, assemblages were comprised of a distinct shallow (<30 m) and deep (>30 m) group, suggesting 30 m as a transition zone between these communities. Shallow specialists had a high probability of being herbivores and deep specialists had a higher probability of being planktivores. Acanthuridae (surgeonfishes), Holocentridae (soldierfishes), and Labridae (wrasses) were associated primarily with shallow habitat, while Pomacentridae (damselfishes) and Serranidae (groupers) were associated with deep habitat. Four species may indicate Central Pacific mesophotic habitat:Chromis circumaurea, Luzonichthys seaver, Odontanthias borbonius,and an undescribed slopefish (Symphysanodon sp.). This study supports the 30 m depth profile as a transition zone between shallow and mesophotic ecosystems (consistent with accepted definitions of MCEs), with evidence of multiple transition zones below 30 m. Disturbances restricted to either region are not likely to immediately impact the other and both ecosystems should be considered separately in management of reefs near human population centers.

Abstract:
Pingelap Island in Pohnpei state is geographically isolated as the nearest island is 70 km away, and such geographical isolation is a challenge for public health due to the limited access to health services. This study aims to reveal the health situation on the island and investigate the influence of geographical isolation on health and diet. For that purpose, the result was compared with those who are living in a community on the main island of Pohnpei state (Mand) with the same ethnic background. Face-to-face interviews were conducted to collect data on demographics, diet, and behavior. Anthropometry and blood pressure measurements were also taken. A total of 98 (Pingelap = 50; Mand = 48) subjects participated in the study. The result showed that females, in particular, had a high prevalence of obesity (80.0% in Pingelap; 75.9% in Mand). However, no significant regional difference was found in both BMI and blood pressure, regardless of gender. Regarding diet, although the geographical location impacted food availability, the consumption of major imported foods did not show a significant regional difference. In conclusion, the geographical isolation did not significantly influence health and diet, but the majority of the study population displayed a high-risk burden of non-communicable diseases.

Abstract:
Heliothrips (Parthenothrips) octarcticulatus was originally described by Schmutz (1913) from Sri Lanka. Subsequently, Hood (1954) described from Taiwan a new genus and species Copidothrips formosus, and then Stannard and Mitri (1962) described a further new genus and species, Mesostenothrips kraussi, from Kiribati and Gibert Islands. Bhatti (1967, 1990), recognized that only a single genus and species was involved amongst these names, established the resultant synonymies, and recorded the species octarcticulatus from various localities between the Seychelles and five different Pacific Island groups. It has also been recorded from Northern Australia, and Thailand (ThripsWiki 2021) as well as Christmas Island in the Indian Ocean (Mound 2019). Despite these records, there is little reliable information about host plants and biology apart from Piper myristicum on Pohnpei island (Micronesia), and also damage caused to the leaves of Aglaonema and Spathoglottis at Darwin in Australia (Mound & Tree 2020). In this note, we add a further interesting host record and describe the previously unknown male as well as the larvae of this species.

Abstract:
As a nation, Federated States of Micronesia (FSM) faces increasing rates of noncommunicable diseases related to the replacement of the traditional diet with processed imported food and adoption of sedentary lifestyles. To reverse this trend, a food-based intervention in Pohnpei, FSM, used various approaches to promote local food (LF) production and consumption. Evaluation of the intervention in one community assessed changes in diet and health status in a random sample of households (n=47). Process indicators were also examined. Results from dietary assessments indicated increased (110%) provitamin A carotenoid intake; increased frequency of consumption of local banana (53%), giant swamp taro (475%), and local vegetables (130%); and increased diversity from LF. There was no change in health measures. However, exposure to intervention activities was high, and behaviour towards LF appeared to have changed positively. It is recommended that the intervention continue and expand to further affect dietary change and improve health.

Abstract:
Food production, or the cultivation and processing of edible materials, is closely linked to both the physical environment and human social systems. This is especially true on the islands of Remote Oceania, where cultivation of plants introduced with colonization has always been a key component of survival. This project centers on the production systems of an island in the west central Pacific: Pohnpei, Micronesia. It addresses the fundamental question of how food production is related to changes in social and physical environments and also addresses the optimum ways to archaeologically study plant remains in tropical oceanic environments with poor preservation. In order to examine these questions, this project looks at human-environment interrelationships using historical ecology. A multi-pronged approach was used in this research. Archaeological survey was used to identify prehistoric and historic features on the landscape and to map the distribution of food production activities. Excavation of selected archaeological features, including breadfruit fermentation pits, yam enclosures, and cooking features, was conducted to examine formation patterns. Paleoethnobotanical analysis included collection and analysis of flotation samples for carbonized plant macroremain analysis and sediment samples for phytolith analysis. Finally, because a reference collection is key to all paleoethnobotanical research, plant specimens from multiple Pacific locations were collected and processed for phytolith reference. Botanical data show that phytolith analysis is very useful in the Pacific region, as many economically important taxa produce phytoliths. However, because of differential silica uptake, it should be used in conjunction with other methods. Archaeological phytolith analysis of the garden landscape shows disturbance caused by pigs, which were introduced historically, a change from the prehistoric phytolith record, which shows no major shifts. Combined analysis of plant macroremains and phytoliths from secure archaeological contexts shows the use of banana leaves in breadfruit cooking in the historic period, highlighting the importance of multi-method paleoethnobotanical study. These data point towards an anthropogenic environment and stable agricultural system that was present in late prehistoric Pohnpei. Major changes occurred in the historic period, although production of plant foods that were important for centuries continues to flourish today.

Abstract:
The traditional Pohnpeian socio-political system has been classified as a complex stratified chiefdom (e.g. Ayres 1990; Cordy 1985; Petersen 1992) and was arguably a state for a few hundred years of the island’s prehistory. Oral tradition documents a period when the island was unified by a dynasty based at the site of Nan Madol, followed by a decentralization of power after the dynasty was overthrown (Bernart 1977; Hambruch 1936a; Hanlon 1988a). Archaeological data support the identification of Nan Madol as a major socio-political center in prehistory, but little is known archaeologically about how power was centralized at Nan Madol and the strategies used to maintain the state prior to its overthrow. The primary questions of this thesis surround the mechanisms of social change in Pohnpeian prehistory, particularly the use of coercion and cooperation as a means of developing and/or maintaining a state-level society. Monumental architecture is often associated with the presence of complex stratified societies and states, and is often referenced in discussions of socio-political development (e.g. Joyce 2004; Kirch 2010; Kolb 1994). Monumental constructions on Pohnpei, particularly those at Nan Madol, have been a point of interest to visitors and researchers since the mid-1800s. Surprisingly, with the numbers of drawings and maps produced of these monuments, little detailed analysis of these structures as a unit has been completed. This thesis addresses questions related to the socio-political development of Pohnpei through the analysis of mortuary monuments and structures. Detailed comparisons of architectural features performing similar functions can produce invaluable information relating to social hierarchy and change. Examinations of architectural change over time may indicate major shifts in a society’s developmental trajectory. This thesis examines monumental mortuary structures in order to examine social strategies in the state period and factors which may have played a role in the maintenance and dissolution the centralized socio-political system. These structures were constructed across the island, including at Nan Madol. The inclusion of burial platforms with the lolong in this analysis will allow for an examination of hierarchical relations between burial types, and identification of potential indicators of socio-political change. This thesis examines architectural styles, scale of architecture, permanent features associated with each structure, and labor invested into the construction process. The analyses of this data will provide information on relative status of architectural features, the management required to construct these structures, differences between sites, and change over time. The results will then be used to discuss the probability of the use of coercive labor mobilization strategies in building construction, and the wider social implications of the use of coercion in architectural projects. This study will examine the incidence of coercive labor mobilization in contrast to cooperative projects as a means of examining the use of coercion and cooperation in prehistoric socio-political dynamics and state politics on Pohnpei. Finally, the results of this thesis will be discussed in relation the application of cooperative and coercive theories of socio-political development in instances where there is little to no archaeological evidence of interpersonal conflict and warfare.
